Datum number in table Q305: Enter the number in
the datum or preset table in which the TNC is to save 
the coordinates of the line intersection. If you enter 
Q305=0, the TNC automatically sets the display so 
that the new datum is at the intersection of the 
connecting lines. Input range 0 to 2999
U
New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC 
should set the calculated intersection of the 
connecting lines. Default setting = 0. Input range: 
-99999.9999 to 99999.9999
U
New datum for minor axis Q332 (absolute):
Coordinate in the minor axis at which the TNC should 
set the calculated intersection of the connecting 
lines. Default setting = 0. Input range: -99999.9999 to 
99999.9999
U
Measured-value transfer (0, 1) Q303: Specify
whether the determined datum is to be saved in the 
datum table or in the preset table:
–1: Do not use. Is entered by the TNC when old 
programs are read in (see “Saving the calculated 
datum” on page 314).
0: Write determined datum in the active datum table. 
The reference system is the active workpiece 
coordinate system.
1: Write determined datum in the preset table. The 
reference system is the machine coordinate system 
(REF system).
